Insert a new dynamic record in JSON under array field

Hi Everybody,
Kindly help.
Am trying to insert a dynamic value under the **value** array using extend function but unable to do so. 
[
{
"entity":
{
"attributes":
{
"type":"CustomField","url":"A"
}
"Metadata":
{
"valueSet":
{
"value":
[
{
"color":null,"default":false,"description":null,"isActive":null,"label":"None","urls":null,"valueName":"None"
},
{
"color":null,"default":false,"description":null,"isActive":null,"label":"Country","urls":null,"valueName":"Country"
},
{
"color":null,"default":false,"description":null,"isActive":null,"label":"Employee","urls":null,"valueName":"Employee"
},
{
"color":null,"default":false,"description":null,"isActive":null,"label":"Both","urls":null,"valueName":"Both"
}
]
},
},
},
},
{
"src_code":"Active","tgt_code":null
}
]







Output:

[
{
"entity":
{
"attributes":
{
"type":"CustomField","url":"A"
}
"Metadata":
{
"valueSet":
{
"value":
[
{
"color":null,"default":false,"description":null,"isActive":null,"label":"None","urls":null,"valueName":"None"
},
{
"color":null,"default":false,"description":null,"isActive":null,"label":"Country","urls":null,"valueName":"Country"
},
{
"color":null,"default":false,"description":null,"isActive":null,"label":"Employee","urls":null,"valueName":"Employee"
},
{
"color":null,"default":false,"description":null,"isActive":null,"label":"Both","urls":null,"valueName":"Both"
},
{
"color":null,"default":false,"description":null,"isActive":null,"label":"Active","urls":null,"valueName":"Active"
}
]
},
},
},
}

    Hi @KTsnap,

    There is multiple ways of adding an element to an array. Besides the .push() method, you can use array concatenation:

    $value.concat([{"color":null,"default":false,"description":null,"isActive":null,"label":"Active","urls":null,"valueName":"Active"}])

    OR

    [...$value,{"color":null,"default":false,"description":null,"isActive":null,"label":"Active","urls":null,"valueName":"Active"}]

    Regards,
    Bojan

      HI Bojan,

      But it can be dynamic depending on the number of inputs.
      its unsure in every run , whether we need to add one element or more than one element to the existing value. How we can implement the same for dynamic values

        @KTsnap, Concatenating can be on multiple elements. In the square brackets, list the elements that need to be added to the original array. That’s basically joining 2 arrays (array1 which is original, array2 which is array of values that need to be added)

      Hi Bojan,
      I tried the above syntax. But its giving only the value inside the array. I need those value along with the input (the way extend works)

        Hey @KTsnap ,

        Here is the array before the expression:

        and here is the array after the expression:

        Re-check if you are doing something wrong. If you were referring to the complete payload, than make sure you check Pass Through in the Mapper.

    Hi @KTsnap,

    If I understood well, you want to add another element to the array, and fields which will be in the new element will be populated from the object which is bellow. Am I right ?

    {
    "src_code": "Active",
    "tgt_code": null
}

      Hi Viktor,
I want to insert new record in the below given array .If suppose there are 4 records under the value array. I want to add the 5th record in the array of value if the another input is  { "src_code" : "Active"}

“value”:
[
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“None**”,“urls”:null,“valueName”:“None”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Country**”,“urls”:null,“valueName”:“Country”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Employee”**,“urls”:null,“valueName”:“Employee”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,**“label”:“Both”,**“urls”:null,“valueName”:“Both”
}
]
{
"src_code":"Active",
"tgt_code":null
}

expected Output 
“value”:
[
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“None**”,“urls”:null,“valueName”:“None”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Country**”,“urls”:null,“valueName”:“Country”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,“**label”:“Employee”**,“urls”:null,“valueName”:“Employee”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,**“label”:“Both”,**“urls”:null,“valueName”:“Both”
},
{
“color”:null,“default”:false,“description”:null,“isActive”:null,**“label”:“Active”,**“urls”:null,“valueName”:“Active”
}
]

      Yes Viktor. and that object needs to be removed in the output. and the number of input object would be dynamic.
      {
      “src_code”: “Active”,
      “tgt_code”: null
      }

    @KTsnap When including JSON or code in a post to this forum, please use the “Preformatted text” feature of this editor. It’s the 6th icon from the left, and looks like this: </>

    This greatly enhances readability, and also allows the content to be copy/pasted in a usable way. If you don’t use the feature on JSON, the editor will modify the double quote characters so that the resulting data isn’t usable if it’s copy/pasted. It also loses all the indentation, which makes it very hard to read.

    Thanks.
